TREATMENT METHOD OF SEWAGE AND WASTE WATER BY USING BOTTOM-UP FILTRATION BIOLOGICAL FILM PROCESS AND ITS APPARATUS

摘要

Purification is related to processing method, device, anaerobic jar or the denitrification tank of a kind of biomembrane process sewage and waste water in the present invention, and partition wall is being installed to predetermined altitude in contact layer between settling tank, tank. HT is from bottom and filtering material layer A, the next door of the bottom, which is formed, contains sewage and O, it is characterized in that the waste water is configured as providing the biomembrane slot of filtering upwards, to form the opening of flowing, it floods rotary sanitary sewage and waste water Yangshan anaerobic reaction scheme and aerobic upper aeration contact filtration reaction treatment method should carry out closed exploitation by Jinxiang layer water flow filtering material or jeokchi decays the various microorganisms of development activities under the continuous souring of tally appropriate and sludge, and it is filtered and acts on while not occurring acutely to filter, if it is carried out in several stages simultaneously, then range is wider, application range and processing efficiency can be made to maximize.
